Answer:

Shreya must put in 3 more cups of sugar.

Step-by-step explanation:

Given that a recipe for cupcakes calls for 6 cups of sugar, and Shreya has already put in 3 cups, to determine how many more cups does she need to put in to complete the amount required by the recipe, the following calculation must be performed:

6 - 3 = X

3 = X

Therefore, Shreya must put in 3 more cups of sugar.

Answer:

if x+y equal 90

and z equal 2 sqrt 61

if you want the real values of the x and y iam not sure but you have to use ratios and proportions Formula for example 24k=90

Answer:

D

Step-by-step explanation:

The volume of the empty space in the cube can be represented by the expression mentioned in the (D) option (D) is correct.

It is defined as three-dimensional geometry when half-circle two-dimensional geometry is revolved around the diameter of the sphere that will form.

[tex]\rm V = \dfrac{4}{3} \pi r^3[/tex]

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

It is given that:

A sphere with a diameter of 9 units fits exactly in the clear glass cube.

Diameter = 9 units

The radius r = 9/2 units

The volume of the sphere:

[tex]\rm V = \dfrac{4}{3} \pi (9/2)^3[/tex]

[tex]\rm V = \dfrac{4}{3} \pi (4.5)^3[/tex]

The volume of cube = a³

a is the side length

The volume of the cube = (9)³

The volume, in cubic units, of empty space in the cube:

[tex]=(9)^3- \rm \dfrac{4}{3} \pi (4.5)^3[/tex]

Thus, the volume of the empty space in the cube can be represented by the expression mentioned in the (D) option (D) is correct.

Answer:

1. 1,538.60 cm³

2. 314.00 m³

Step-by-step explanation:

1. Given:

Diameter = 14 cm

Radius (r) = ½(14) = 7 cm

height (h) = 10 cm

π = 3.14

Volume of cylinder = πr²h

Plug in the values

V = 3.14*7²*10

V = 1,538.60 cm³

2. Given:

Radius (r) = 5 m

Height (h) = √(13² - 5²) = √144 = 12 m

π = 3.14

Volume of cone = ⅓πr²h

Plug in the values

V = ⅓*3.14*5²*12

V = 314.00 m³

The percentage of the rate of decrease in the medication will be 75%. Option A is correct.

The exponential function is characterized as a function that increases quickly and whose value is always positive. With the exponent y = aˣ, where a is the constant and a>1.

It is given that the function is,f(x) = 500(0.75)ˣ. The number x represents the number of hours since the patient took their medication.

f(x) = 500(0.75)ˣ

Compare the function with the standard function as

y=baˣ

Where b is the constant value, a is the percent of the rate of decrement and x is the time period,

The value of a for the given function will be 0.75. The value is in percentage form and can be written as,

=0.75 ₓ 100

=75%

Thus, the medication's rate of decline will be 75%. Option A is correct.

Answer:

B: The center of data is shown by the mean, which is 43.

Step-by-step explanation:

Add up all the digits (33+38+38+40+44+51+57)/7=43 the mean. The mean is always teh center of data so it's B. Hope this helps.

Answer:

Hence, the confidence interval is [tex](63.517,74.483)[/tex] gallons.

Given :

Sample size[tex]=36[/tex]

Sample mean [tex]=69[/tex] gallons

Standard deviation [tex]=20[/tex] gallons

So, the standard error [tex]=\frac{20}{\sqrt{36}}=20/6=3.33[/tex]

Confidence level [tex]=95\%[/tex]

To find :

The [tex]95\%[/tex] confidence interval for the number of gallons of carbonated beverages consumed per year by Americans.

Explanation :

[tex]\because[/tex] Confidence interval [tex]=(\text{Sample mean}-\text{margin error},\text{Sample mean}+\text{margin error})[/tex]

Margin error [tex]=Z_{\frac{\alpha}{2}}\times\frac{\sigma}{\sqrt{n}}[/tex]

Here, [tex]\alpha=1-95\%=1-0.95[/tex]

      [tex]\Rightarrow \alpha=0.05\Rightarrow \frac{\alpha}{2}=0.025[/tex]

    [tex]Z_{\frac{\alpha}{2}}=Z_{0.025}=1.645[/tex] from the [tex]z-[/tex]table.

So, Margin error [tex]=Z_{\frac{\alpha}{2}}\times\frac{\sigma}{\sqrt{n}}[/tex]

                         [tex]=1.645\times\frac{20}{6}=1.645\times3.33[/tex]

                        [tex]=5.483[/tex]

Therefore, the confidence interval is:

   [tex](69-5.483,69+5.483)[/tex]

[tex]=(63.517,74.483)[/tex] gallons.

  VU : UW : WV = 27 : 39 : 52 (reduced)

  DC : CE : ED = 12 : 19 : 24 (reduced)

The side length ratios are different, so the triangles are NOT SIMILAR.

Thus substitute:

simplify multiplication:

since 144>100 it's our answer

the other options don't satisfy the condition

The rectangular prism with dimensions of 2 by 12 by 6 and the cube with a side length of 4 have volumes greater than 100 cubic units.

A prism is a three-dimensional object.

There are triangular prism and rectangular prism.

We have,

The two figures that will have a volume greater than 100 cubic units are:

A rectangular prism with dimensions of 2 by 12 by 6

Volume = length x width x height

= 2 x 12 x 6

= 144 cubic units

A cube with a side length 4

Volume = side x side x side

= 4 x 4 x 4

= 64 cubic units

Therefore,

The rectangular prism with dimensions of 2 by 12 by 6 and the cube with a side length of 4 have volumes greater than 100 cubic units.

Answer:

Hence, the score for each of the five observations are [tex]-1.25,1.25,-0.75,0.50,0.25[/tex]

Given :

Sample with data values of [tex]x_i[/tex]  [tex]10,20,12,17[/tex] and [tex]16[/tex]

Sample size[tex]n=5[/tex]

To find:

Compute the score for each of the five observations.

Explanation :

[tex]\because[/tex] Sample mean [tex]\bar{x}=\frac{\sum x_i}{n}[/tex]

                     [tex]\Rightarrow \bar{x}=\frac{10+20+12+17+16}{5}=\frac{75}{5}[/tex]

                    [tex]\Rightarrow \bar{x}=15[/tex]

Standard deviation [tex]\sigma=\sqrt{\frac{\sum (x_i-\bar{x})^2}{n-1}}[/tex]

                             [tex]\Rightarrow \sigma=\sqrt{\frac{(10-15)^2+(20-15)^2+(12-15)^2+(17-15)^2+(16-15)^2}{5-1}}[/tex]

                            [tex]\Rightarrow \sigma=\sqrt{\frac{(-5)^2+(5)^2+(-3)^2+(2)^2+(1)^2}{4}}[/tex]

                           [tex]\Rightarrow \sigma=\sqrt{\frac{25+25+9+4+1}{4}}[/tex]

                          [tex]\Rightarrow \sigma=\sqrt{\frac{64}{4}} =\sqrt{16}[/tex]

                         [tex]\Rightarrow \sigma=4[/tex]

[tex]\because[/tex] The score of the observations [tex]Z[/tex] is [tex]\frac{x-\bar{x}}{\sigma}[/tex].

So, when [tex](x=10),[/tex]       [tex]Z=\frac{10-15}{4}=-1.25[/tex]

     when [tex](x=20),[/tex]       [tex]Z=\frac{20-15}{4}=1.25[/tex]

     when [tex](x=12),[/tex]      [tex]Z=\frac{12-15}{4}=-0.75[/tex]

    when  [tex](x=17},[/tex]       [tex]Z=\frac{17-15}{4}=0.50[/tex]
